Name of the Vulnerable Software and Affected Versions yasm version 1.3.0.55.g101bc

Description A stack overflow issue was discovered in the parse expr5 function at /nasm/nasm-parse.c. This issue has been disputed by third parties, arguing it is a bug rather than a security issue, as yasm is a standalone program not designed to run untrusted code.

Recommendations For yasm version 1.3.0.55.g101bc, as a temporary workaround, consider restricting the use of the parse expr5 function until a patch is available. At the moment, there is no information about a newer version that contains a fix for this issue.
